Question

I am creating a service which will be consumed by presentation program. I am at a fork of defining my types as class or struct. Does .Net create 1 stack(to store value types) for each dll and exe or 1 stack per program. I am very sure it creates one Managed heap per program but not sure of stack. Please help me.

Thanks,
Omkar

Answer 1

Firstly The Stack Is An Implementation Detail.

As it happens there is 1 heap* per process and 1 stack per thread in a process, but you shouldn’t care about this and certainly shouldn’t use this when choosing between classes and structs.

See When to use struct in C#?

(*) Well, 1 managed heap anyway.
